Passing parameter using variable While generating DSC configuration

Question

I am executing Powershell DSC script from Powershell. Below is the code snippet

Invoke-Command -ComputerName $public_ip_address -Credential $UserCredential -ScriptBlock {
    param ($driveformat)
    cd c:/provisioning
    Install-PackageProvider -Name NuGet -Force -Scope CurrentUser
    Install-Module -Name PSDscResources -Force
    Install-Module -Name xStorage -Force
    . .\DiskSetup.ps1
    disksconfig -outputpath C:\DataDiskSetting -driveFormat $driveFormat
    Start-DscConfiguration -Path C:\DataDiskSetting -Wait -Force -Verbose
} -ArgumentList ($driveformat)

While generating configuration I want to pass driveformat as variable "$driveFormat" instead of hardcoding like "NTFS". Somehow its not getting value of $driveformat any idea how we can solve this.

You don't show where you define `$driveformat` – Doug Maurer Sep 08 '20 at 06:58 — Doug Maurer, Sep 08 '20 at 06:58
It is passed as Parameter from pipeline in PS Script. – bhupinder Sep 08 '20 at 07:04 — bhupinder, Sep 08 '20 at 07:04
OK, how can we help you determine why it's empty? – Doug Maurer Sep 08 '20 at 07:15 — Doug Maurer, Sep 08 '20 at 07:15
Value is passed from Pipeline for example "NTFS" – bhupinder Sep 08 '20 at 07:44 — bhupinder, Sep 08 '20 at 07:44

You can add a named Parameter $driveformat in your script. See below example:

Param([String]$driveformat)

Invoke-Command -ComputerName $public_ip_address -Credential $UserCredential -ScriptBlock {
    param ($driveformat)
    ...
} -ArgumentList ($driveformat)

Then in the powershell task from pipeline, add -driveformat "NTFS" in the argument field. See below screenshot: (I defined a pipeline variable driveformat to hold the value "NTFS")

Or, you can add an Argument (eg. $driveformat = $args[0]) in your scripts. See below:

$driveformat = $args[0]

Invoke-Command -ComputerName $public_ip_address -Credential $UserCredential -ScriptBlock {
    param ($driveformat)
    ...
} -ArgumentList ($driveformat)

Then you can directly pass the variable ("NTFS") in the Arguments field of powershell task:
